Question

NADPH is synthesized during

• A. Cyclic photophosphorylation
• B. Non-cyclic photophosphorylation
• C. Splitting of water
• D. Both a and b

Answer 1

The correct option is B Non-cyclic photophosphorylation

Cyclic photophosphorylation occurs when plants have enough of NADPH and need only ATP. So, no NADPH is generated.

Non-cyclic Photophosphorylation involves both the photosystems. NADPH, ATP and oxygen are the three products of non-cyclic photophosphorylation.

Splitting of water is a part of non-cyclic photophosphorylation and yields oxygen, protons and electrons.
